Hi Henry,
Thank you for taking the time to respond in such detail to my question and stating that you do think there's a direct relationship between an analog power supply and good bass response in an amp. Given your praises of regulated amp output voltage, which the switching mode has but which the analog power supplies typically lack due to expense, I would have thought the relationship between an analog power supply and good bass response would be less direct. However, I'm fairly certain it's best to defer to your knowledge and experience on this matter.
It's very interesting and encouraging to know that you're continuing to explore the potential of the somewhat newer class D power modules such as the Hypex NCore 400 modules along with corresponding Hypex switching mode power supplies. I would be very interested to know if you discover varying performance levels between these modules paired with the various Hypex smps (NCore 1200 and 600 smps) and the NCore 400 modules paired with your own analog power supply.
Strictly from my subjective viewpoint, the most obvious differences I've noticed between using class D and various class A/B amps(Adcom, McCormack and Aragon) in my system are improved bass response, a reduced noise floor, increased dynamics (especially on content recorded in hi-res 24/96 format), increased detail and a more neutral sonic character in general.
These benefits were clearly noticed on the first 2 class D amps I owned (Class D Audio SDS-440-CS and Emerald Physics EP-100.2) and these qualities are even more clearly noticed on my current class D amps (D-Sonic M3-660-M).
Just to be clear, I was not offended with anything you said and agree that there is no absolute in this hobby.
Thanks Henry,
Tim
